They look OK with (3) but might look even better with (4) - add one between your thumb and the 1st lit LED in pic.
Almost need to see each beside one another to tell.
Important thing with these is that the housing fits properly to fender with no gaps, be nice if they also had built in gasket as OEM, and they need to be sealed well to prevent any interior build up of condensation.
The versions out there right now (with exception to DEPOT sidemarkers on eBay) all have crappy fitment and leave a gap between housing & fender unless modified, regardless of 100% fitment claims, and within 2 weeks they are full of condensation. - a total waste of $70 been there, done that
It should be noted that the DEPOT sidemarkers do not contain their own LED's - they are simply housings that allow for smoked/tinted look - you still need to buy LED bulb for that LED look, & then there is obviously only (1) LED.
I currently use the DEPOT smoked sidemarkers with HPB LED bulb & am happy with them - but a version with multiple built-in LED's would be great (if they meet all the requirements I mentioned)
And of course, regardless of whether they are CanBus or not - they will need coding to eliminate the flickering upon startup due to OEM bulb checks...
